向赠品命令discord.py添加计时器

Question

我试图创建一个带有赠品命令的不和谐机器人，该命令每 1-2 分钟更新一次赠品嵌入中剩余的时间。我已经尝试了 3 天，但未能找到解决方案。我设法让它更新秒数，但如果我指定的时间超过 1m，即 60 秒，它会自动将其转换为秒，并开始赠品，剩余时间为 just 秒 。我希望它以给定单位保留时间并以--天、--小时、--分钟、--秒为单位更新时间。

这里有一些图片，我的意思是：

目前做什么：

我想要它做什么：

它只是结束于或时间剩下我想要改变的！

我当前的代码：

@commands.command()
    @commands.guild_only()
    async def gstart(self, ctx, duration, *, prize):
        time = self.convert(duration)
        if time == -1:
            await ctx.send(f'Answer Time With A Proper Unit (s, m, h, d)')
            return
        elif time == -2:
            await ctx.send(f'Time Must Be A Integer!')
            return
        giveawayembed = discord.Embed(
            title="🎉 New Giveaway! 🎉",
            description=f"**Prize:** {prize}\n"
                        f"**Hosted By:** {ctx.author.mention}\n"
                        f"**Ends In:** {time} Seconds",
            colour=discord.Color.green()
        )

        msg = await ctx.send(embed=giveawayembed)

        reactions = await msg.add_reaction("🎉")

        while time:
            await sleep(10)
            time -= 10
            giveawayembed.description= f"**Prize:** {prize}\n**Hosted By:** {ctx.author.mention}\n**Ends In:** {time} Seconds"
            await msg.edit(embed=giveawayembed)

        new_msg = await ctx.fetch_message(msg.id)

        users = await new_msg.reactions[0].users().flatten()
        users.pop(users.index(self.client.user))

        winner = random.choice(users)

        endembed = discord.Embed(
            title="Giveaway ended!",
            description=f"Prize: {prize}\nWinner: {winner.mention}")

        await msg.edit(embed=endembed)
        await ctx.send(f"🎉 Giveaway Winner: {winner.mention} | Prize: {prize}")

我有转换时间：

class Giveaway(commands.Cog):
    def __init__(self, client):
        self.client = client

    def convert(self, time):
        pos = ["s", "m", "h", "d"]
        time_dict = {"s" : 1, "m" : 60, "h" : 3600, "d" : 3600*24}
        unit = time[-1]

        if unit not in pos:
            return -1
        try:
            val = int(time[:-1])
        except:
            return -2

        return val * time_dict[unit]

非常感谢任何帮助！ 😁 如果我没能让你理解我的问题，我很抱歉。 😅

我理解你的问题，因为它实际上是一个非常简单的修复，你可以导入时间，或使用

await asyncio.sleep(time)

在使用我提供的代码之前，请确保在导入中添加

import asyncio

。

您的代码：

    @commands.command()
    @commands.guild_only()
    async def gstart(self, ctx, duration, *, prize):
        time = self.convert(duration)
        if time == -1:
            await ctx.send(f'Answer Time With A Proper Unit (s, m, h, d)')
            return
        elif time == -2:
            await ctx.send(f'Time Must Be A Integer!')
            return
        giveawayembed = discord.Embed(
            title="🎉 New Giveaway! 🎉",
            description=f"**Prize:** {prize}\n"
                        f"**Hosted By:** {ctx.author.mention}\n"
                        f"**Ends In:** {time} Seconds",
            colour=discord.Color.green()
        )

        msg = await ctx.send(embed=giveawayembed)

        reactions = await msg.add_reaction("🎉")

        while time:
            await sleep(10)
            time -= 10
            giveawayembed.description= f"**Prize:** {prize}\n**Hosted By:** {ctx.author.mention}\n**Ends In:** {time} Seconds"
            await msg.edit(embed=giveawayembed)

        new_msg = await ctx.fetch_message(msg.id)

        users = await new_msg.reactions[0].users().flatten()
        users.pop(users.index(self.client.user))

        winner = random.choice(users)

        endembed = discord.Embed(
            title="Giveaway ended!",
            description=f"Prize: {prize}\nWinner: {winner.mention}")

        await msg.edit(embed=endembed)
        await ctx.send(f"🎉 Giveaway Winner: {winner.mention} | Prize: {prize}")

在这两个修复中，我都会修复一个很容易修复的小问题，所以当时间到来时，它会减少 10，我建议这样做，这样它就会显示

while time > 0:

，这样一旦它达到 0，它就不会继续计数下来。

使用

await asyncio.sleep(time)

轻松修复：

    @commands.command()
    @commands.guild_only()
    async def gstart(self, ctx, duration, *, prize):
        time = self.convert(duration)
        if time == -1:
            await ctx.send(f'Answer Time With A Proper Unit (s, m, h, d)')
            return
        elif time == -2:
            await ctx.send(f'Time Must Be A Integer!')
            return
        giveawayembed = discord.Embed(
            title="🎉 New Giveaway! 🎉",
            description=f"**Prize:** {prize}\n"
                        f"**Hosted By:** {ctx.author.mention}\n"
                        f"**Ends In:** {time} Seconds",
            colour=discord.Color.green()
        )

        msg = await ctx.send(embed=giveawayembed)

        reactions = await msg.add_reaction("🎉")

                while time >= 0:

                time -= 10
                await asyncio.sleep(10)
            elif 60 <= time < 3600:
                giveaway.remove_field(index=1)
